I have run maleware..S.A.S. I use Avast. It started after computer crash, when I had to re-install everything. Not sure if it could be Microsoft, as can't get rid off there cookies Microsoft.com and ieonline.com. I get rid off them and they keep coming back. Thanks for help centaur,

I would usually advise downloading some other diagnostic software, but since you don't seem to be able to do this, at least using IE 10, would you please try and use say Google Chrome, which should have been loaded on your Windows system as one of the alternative, and imo, very easy to use, alternatives to IE ?

It will give you an option to import all of your favourites/bookmarks from IE when you begin using it.

Short of offering to give you one to one help by taking over your computer online, I'm struggling to see why or how this problem arose, so would you at least have a go at trying to use an alternative browser to see if it makes any difference ?

I know you can do it, we all can with a bit of help !

Usually all Windows systems including and after Vista were forced by EU law to include alternative browsers as part of the system. Have you checked in the 'all programs' list ?
In most cases I think there is an icon on the desktop which allows this choice as well.
Alternatively, can you start the computer in 'safe mode' and try Internet Explorer from there and see if it will allow downloading ?

Do you still get notifications of windows updates and can you download and update ok?

If you can do this, one of those updates is to get the latest version of Internet Explorer IE 11, which I use. It's basically a slightly quicker version of IE 10, so update to this if you can, and hopefully, unless your 'puter has a very nasty bug, you should be able to download.

Best of luck.
